HELP!! MSFT Word documents printing out in “REVERSED/MIRRORED” way.

HELP!!! I am not sure why this happened or how; but yesterday Toshiba laptop with Windows XP SP3 using HP Off.Jet 7700 series printer decided to print some word documents in a “mirrored” fashion, you know, like hold the page in front of a mirror to read it. Both working normal till yesterday afternoon. Tried printing some other things; ie: notepad and emails and they come out printer perfect, but still any saved MS Word documents tried to print from various My Docs file come out printer “REVERSED.”
Anyone have a clue, what happened, why and ideas on fix, PLEASE ENLIGHTEN ME, I’m going nuts over this one…Thanx, RIDE FREE & SAFE, Lil’ ndn.
